Fig. V is a view is bent at an angle, so as tobring its one end of the same, but the plug being turned to over thefloat 17, while its other end will be place the hydrant or watersupplypipe and directly over the valve-seat I3, and it is con; trap incommunication. Eig. VI is an ennected at the aforesaid end to the saidfloat larged detail section taken on the line VI VI, by means of a linkor connectingrod 23,while Fig. II. Eig. VII is an enlarged detail viewof at its opposite end 'it is attached to a valve the float-levershereinafter described, showing 24, resting upon the seat 13 and closingcomroo them in their proper positions relatively to munication betweenthe two compartments each other. Fig. VIII is an enlarged detail bymeans of a rod or link 25.

o view of the compound cock in vertical sec- Secured in the bottom ofthe trap 2, on the tion, taken on line VIII VIII, Fig. V, showoutside ofthe annular wall or partition l2, is :ing it in position to establishcommunication a valvehousing 2G, having a flange 27, resting 105 betweenlthe hydrant and trap, and also beupon and secured to the bottom of thetrap by means of bolts 28, as show n. this housing is a three-waycompound valve or cock 29, having two series of three-way ports arrangedone above the other, as shown in Fig. I, and the housing is likewiseprovided With corresponding ports. The upper ports 30, 3l, and 32 (seeFigs. I, VIII, and IX) of the housing communicate, respectively, withthe boiler by means of the pipe 33, with the upper portion of the tankor trap 2 by means of the elbow 34 and stand pipe 1 35, (which, asshown, extends above the parrectly to the boiler, I prefer to connectthem.

the one 33 in the head or upper end and the one 39 near the bottom of abarrel or tank 42, which is itself connected at top above the water-lineand at bottom below the water-line to the boiler by means of short pipes43 44, respectively. Thus it will be seen that the boiler is connectedabove its water-line with the trap above thewater-line of the latter byumeans of one duet and below the water-line with the bottom of the trapby means ot a separate duct; or, in other words, the spaces above andbelow the water-lines in the trap and boiler are respectively connectedby means of separate ducts,which may be simultaneously opened or closedby a quarter-revolution of the compound cock 29.

On the upper end of the cock 29 is an axial tenon 45, on which issecured, by means of a key 46, a bevel-pinion 47,with which latterengages a circular beveled segment-rack 48. This rack 4,8 is journaledupon a pint-le 50, extending between the upper ends ot two standards orbrackets 5l 51X, planted in or made integral with the flange 27, and thebracket 5l carries a box 52,`in which is journaled ythe upper end of thetenon 45, whereby the plug is held rigidly in place. The inner end ofthe 4lever 2l is connected to one side ot this segment-rack by means ofa rod or link 53 and a pivot-pin 54, made integral with the corner ofthe rack, while the outer end of this lever has suspended from it, bymeansot a rod 55, a heavy float 5(3,which covers approximately the wholesupercial area of the compartment 10, and is rounded outor cut away atits mid-length 57,'in order that it may not interfere with the operationof the valve 24 and its stem or rod 23.V This float, as well as the one17, may be of any of the well-known kinds, and the rods may be securedto them in any suitable and desirable manner.

The pipe 33,which connects the space above Situated in or mouth 59 issealed by the water in the barrel (which level is of course the same asthe level in the boiler) the water gravitatingfrom the tank or trap willstop for the want of pressure aboveit, the steam-pressure through thepipe 35 being checked by the rise of the water in the barrel above thepipe-mouth 59. Therefore the normal (and in fact permanent) water-levelmay be fixed at any height, according to the location of the mouth 59 ofthe extension, and if it should be desired to change 'the water-level itis only necessary to remove the plug 60 from the head ot the barrel andreplace the extension by one of different length, the extension beingscrewed into the lower end of the plug v60, as shown.

When there is no water inthe well 16 or the compartment lO, the iioats17 56 will of course descend, and in so doing the former 17 will operatethe segment 48 to turn the cock one-fourththe way around in the positionshown in Fig. V, in which position all communication ma the pipes 39with the boiler or barrel 42 is entirely cut off, while the upper seriesof ports in the cock-plug 29 place the air-port 3l and port 32, leadingto the stand-pipe 35, in communication, as shown in Fig. IX, and thelower series place the hydrant-supply pipe 4l and pipe 40, leading tothe bottom of the trap, in communication. Thus it will be seen that thewater from the hydrant will iiow into the trap 2, entering first thecompartment 9 on the opposite side of the partition l24 to the well orpit 16, and will rise until it overtlows said partition or wall, and,filling the well, will cause the iioat l7 to rise and thereby force thevalve 24 to its seat with considerable pressure. None of the water,however, will enter the compartment 10 before the valve 24 is closed,and thereby lighten or raise the iioat 56, for the reason that thevalve-seat 13 is on a higher level than the top of the partition l2, sothat the water will iill the well and close the valve 10 before it risesabove the said valve-seat; or to further insure against the waterentering the compartment 10 ma the valve 24 the port 14 may be providedwith a butterflyvalve 62, as shown in Fig. X. Thel valve 24 being nowhermetieally closed, the water will continue to rise in the compartment9 without running into the compartment l0 at all until its level reachesthe aperture 61 in the partition 8, whereupon it runs through and beginsto lill the compartment l0 and begins to raise the float 56, andconsequently turns the valve 29, so as to cut off the flow of water fromthe hydrant-pipe 4l. and also the air- IOO IIO

of the water in the compartment stopped when the supplyfrom the pipe i1was cut o the iioat would only be buoyed up sufficiently far to barelyclose the air-port 32 and supply-port 3S, as just mentioned, whilecommunication between the boiler and the trap niet the pipes 33 39 34:40 would still be closed. Therefore the water is allowed to enter thecompartment 10 at a less rate than it enters the compartment 9, so thatalthough the level of the water has reached the aperture 61 it willnever- .theless continue to rise above it, and may even overfiow thepartition 8 before sufficient has run through the aperture 61 to raisethe float 56 all the way, so that after the water reaches the top of thepartition S in the compartment 9 there will still be enough above theaperture 6l to run into the compartment 10 and buoy the floatsufficiently high to turn the cock all the way-that is, with its portscommunicating with the pipes 33 39 34 40, respectively. Communicationwith the boiler now being opened, the steam will enter the trap throughthe stand-pipe 35, and the hot Water from the boiler will enter ma thepipe 40, thus equalizing the pressure in the trap and boiler andallowing the water from the trap to fiow by virtue of gravity down thepipe 39 and thence into the barrel 42 and boiler until it rises to sucha level as to cover the mouth 59 of the extension 58, thus stopping offthe pressure of steam at the top of the water in the trap 2, andconsequently preventing a further quantity of water from flowing downthe pipe 39 into the barrel.

The water in exhausting from the trap 2 will entirely run out of thecompartment 9 before any leaves the compartment l0, the water in thewell 16 in said compartment 9 being of course the last to leave thetrap, and it exhausts from this well ra the duct 63, which leads to thepipe 40 and is provided with an outwardly-opening valve 64, whichpermits the outow from the Well, but prevents backiiow from the pipe 40.As the valve 2i is now bearing a great deal of pressure from the waterin the compartment 10, it will remain on its seat until the water hasnearly left the iioat 17 but as the water sinks the iioat will graduallypreponderate and suddenly raise the valve 2i from its seat with a jerk,allowing the volume in the comparte ment 10 to rush outand -descend intothe boiler, but is prevented from first passing into the well 16 (whichwould cause the float therein to rise and again close the valve 24) byreason of the partition 12 in the trap and the check-valve 6i in theduct 63. This release of the water in the compartment 10 will cause thefloat 56 to descend rapidly and suddenly turn the cock 29 back to theposition indicated at Figs. V, VIII, and IX, shutting off the connectionwith the boiler and opening communication with the hydrant andatmosphere.

It will be seen that if the iioat 56 were allowed to descend graduallywith the water in the compartment 9 communication between the boiler andtrap would be shut off before the valve had turned far enough to opencommunication with the hydrant; hence it is essential to have the waterin the compartment 10 remain until the compartment 9 is emptied, so thatwhen the Water in compartment 10 is once released it cannot again assumea level sufciently high to prevent the descent of the float 56 eventhough it does not leave the compartment 9.

The lower end of the plug 29 is provided with a usual indicator 65, toshow at all times the position of the ports in the plug.

It will ofcourse be understood that the barrel or tank Ll2 may beomitted and the two pipes 33 39 connected directly with the boilerwithout deviating from the spirit of my invention.
